/diy/ - Do It Yourself

brute fucking force, probably. a yuuuge transformer, followed by four yuuuuuuge diodes, followed by a yuuuuuuge capacitor bank. just like the old-style unregulated wall-warts but scaled way up, made with square bar instead of enamel-coated copper wire
also those diodes would go on a big ass heatsink because 0.6V * 600A ~= 360W of pure heat loss. maybe active cooling would be a good idea
maybe I'd just call up the local telco and see who they use for the similarly dimensioned power supplies in their central offices
